Specification forming part of Letters Patent No. 3 l lfi, dated January 15, 1856.

this specification, in which Figure l is an end or muzzle view; Fig. 2, a view of the side with the stock removed; Fig. 3, a longitudinal section, and Fig. 4, a crosssection taken at line A a of Fig. 2; e The same letters indicate like parts in all the figures. Y

The first part of my said invention relates to that class of fire-arms in which a series of barrels are arranged or formed about and turn on a common center that the several charges may be brought in succession around to the hammer'of thelo'ck to be discharged; and my said invention consists in mountingthe central bore of such a series of barrels on a central rotating} arbor which carries the breech-plate for allthe. chambers or barrels, so that the series of barrels can slide thereon to be pushed forward from the breech -plate to receive the charges into the open rear end thereof and then pushed back and locked againstthe breech- 'plate to inelose thecharges, the said central arbor being so mounted in the stock, breechpiece, or lock-frame, and so connected with the look as to be turned by drawing back'tlie finger-lever for the purpose of bringing the barrels successively in line-to be discharged; and my said invention also consists in elevating the cock by a finger-lever so combined with a trigger that the cock can be elevated and there held by a catch to be liberated for the discharge; either by touching the trigger with the finger or by continuing to pull the said finger-lever after elevating the cock and making it act upon the trigger. 1

In the accompanying drawings,a represents a series of barrels made out of one block of metal, the several bores or barrels being arranged in a circle at equal distances around a central bore, which is fitted to a central spindle or arbor, b, on which the series of barrels can slide longitudinally, and to which they are feathered or othe wise so connected as to turn therewith that the several barrels may be brought in succession to be tired. Toward the rear end the said spindle or arboris formed or provided with abreech-plate, c, the front face of which closes all the barrels a when forced and held against it. On the front end ofthe spindle there is a turning key, d,'which, when turned in the position represented in the drawings, holds the barrels firmly against the breech-plate to eoiitine the charges; but the central bore for a short, distance from the muzzle is cut out of a form corresponding with the form of the turning-key (I, so that when the key is turned to the proper position the barrels can be pushedlorwardfrom the breechplate to a sufiicient distance to admit of inserting the charges into the rear end of the barrels and then pushed back and locked.

From the front face of the breech-plate prothat one will correspond with the center of the bore of each barrel; andby reason of this arrangement, after the-cartridges havebeen inserted and the series of barrels are pushed back, the cartridges are punched to expose the powder to the touch-holes, which pass through the centers of these punches to the nipples f on the rear part of the breech-plate.

The rear face of thebreeeh-platectits against the forward face of the metallic breech-piece 0r shield-plate g of the lock-frame or stockis fitted to turn, in the manner of ajonrnal, in

extends back, 'andits rear end is fitted to turn in the rear stock-plate,as at i, and in this way the spindle is held firmly and cauturn freely. Just back of the shield-plate a ratchet-wheel, j,-is secured to the spindle I), the number of teeth in the said ratchet wheel being equal to and correspondin gin position with the-series of barrels. There is a'spring catchflc, which takes into the teeth of the ratchet to hold and keep the spindle from turning at the end of each operation; and this catch is disengaged and the spindle rotated at each operation to bring anotherbarrel in line by the forward end of aspring-hand, I, attached to a lever, m, which atits rear end turns on a fulcrum-pin, m, in the stock-plate or look frame. This lever has an inclined slot or mortise, a, which embraces a wrist-pin, 0, 0n the side of the inner end of a finger-lever, 12, so that by pulling back the finger-lever the wrist travels in the said mortise andelevates the forward end of the lever m, which brings the front face of the springject a series of pointed punches, a, so locatedplate It. The spindle, back of the breech plate,

a central hole in the shield-plate and thence it. The finger-lever is forced 'part of the body of the cock at 10,

hand behind the spring-catch k to lift it out of and to liberate it from the ratchet, while at the same time the said hand ,acts on one of the teeth of the ratchetaudturnsit to the required distance equal to one tooth to turn the barrels and bring a new cha'rgein line.

The end of the spring-handlis so formed .that in rising it'first disengages the springcatch, then turns the ratchetand permits the spring catch to fall back to relock the ratchet-- wheel when tinned to the required extent,and having completed these operations, in returning to its original position it springs outward to pass thespririg-catch without disengaging back to its forward position at the end of the motions above described by a spring, q, which acts on the inner end thereof.

The forward upper part of the finger-lever is formed with a lip, as at 1', which actson a corresponding but in vertad lipon a spring-dog, s, fitted and jointed in a socket in the body of the cock t, which turns on'the fulcrum-pin u, so that when the finger-lever is drawn back the lipr on its forward end acts on the correspondinglip on the dog and forces it downward, which turns the cock on its fulcrum-pin,- thereby elevating the hammer and contracting the mainspring a, which bears on the forward on the opposite side of the fulcrum-pin, and so soon as the hammer is elevated the rear end. thereof at a: is caught and held by a spring-catch, 1

which holds it. The finger-lever is prevented from moving back any farther by a stop,,z,

the lower stockated by the finger it is thrown back to its original position by the tension of the spring q,

condition for the 'discharge by a trigger, c, the sear d of-which acts on the spring-catch y, which liberatesthe cock orliam mer for the discharge.

This tl ig ger can be operated to liberate the cock either by the-finger acting directly on it'atter the cock has been elevated by the fiu'genlevcr, as above described, or by the continued pull of For this purpose the stop; is so connected with the finger-lever that it can slide thereon, and when drawn down to the position represented by dotted lines in Fig.

3 it does not arrest the back movementof the linger-lever, which, after-cocking the hammer, strikes againstthe trigger and etfects the'discharge by the one continued pull on the fingerlever. But to do this the finger-lever, after elevating the cook or hammer, must permit the dog to pass by it as the cock or hammer descends, and for this purpose the continued Y which liberates the catch 3/, that the mainspring may force .fown the cook or hammer, as if the trigger were operated directly by the tinger. In this way the ar'm can be so set by simply shifting the sliding or simply cocked to be usual way, and in either case the finger will be relieved from the tension of the mainspring before the discharge, that aim may be taken for the discharge.

s It will be obvious that either of my'saidimprovements may be used without the other, although. thebest results'will. be obtained when both are used in connection. After the discharge the finger-lever is liberated, and it i: then carried back by the spring q, the spring dog 8 yielding to permit the lip '1' on the tinger-lever to pass by and get above the lip on the dog a.

I do not claim as of iny invention the cartridge-cutters on the breech-plate, nor any of the separate parts of which my improved arm is composed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. Mounting the series of barrels on a can,

tral rotating spindle or arbor provided. with a breechplate, so that it can slide'thereo'm'substantially as described, to be moved forward to receive the charges and then pushed back and locked to inclose the charges, as set forth.

2. The method of elevating the cockby the finger-lever until it is engaged and held by a spring-catch, substantially as described, in combination with the trigger, 'so arranged that it can be operated by the continued pull of the finger-lever to effect the discharge, substnm tially as described. A

3. In; combination with the finger-lever and trigger, arranged and combined substantially as specified, the employment of the shifting stop'on the finger-lever, so that it can be set, veither to efiect the discharge by the continued back pull on the fingerlever or by touching the trigger with the finger after the cock has been elcvated',"as described.
